A 52-year-old man presented for an annual physical in January 2007, where a screening PSA and DRE were performed. A serum PSA of 7.0 was detected, and on digital rectal exam, asymmetric nodules were detected. A transrectal biopsy, the gold standard for prostate cancer diagnosis, revealed the presence of carcinoma. A radical prostatectomy was performed in February, the preoperative PSA level was 7.1 ng/ml. PSA level 1 month postop undetectable 1. Was a prostatectomy performed on this patient because of an elevated PSA? 2. Is there any evidence for residual disease in this patient at one month? 3. Will additional PSA levels be necessary, why/why not?.
